Some Lockyer groundwater reserves nearly full

Dr Matthias Raiber from the National Centre for Groundwater Research says water levels have risen by as much as 10 metres and the quality has also vastly improved.

He says some reserves nearly ran dry during the drought.

"I started working on the Lockyer Valley maybe half a year before the floods and I looked at the water levels and they were still very low and their was the question [of] how long it would take the water levels to recover and I didn't expect that to happen so fast," he said.

Dr Raiber says the quality of the water has also improved.

"Because different crops can take different groundwater salinity and now with this recharge event, the associated freshening of the groundwater, they can use the water for much more diverse forms of irrigation again," he said.
